An MRAM device having a plurality of MRAM cells formed of a fixed magnetic
layer, a second soft magnetic layer and a dielectric layer interposed
between the fixed magnetic layer and the soft magnetic layer. The MRAM
cells are all formed simultaneously and at least some of the MRAM cells
are designed to function as antifuse devices whereby the application of a
selected electrical potential can short the antifuse device to thereby
affect the functionality of the MRAM device.
